Technical Field
[0001] The utility model belongs to the technical field related to screening equipment, and specifically relates to a vertical fiber crushing and screening equipment. Background Art
[0002] Vertical fiber crushing and screening equipment is a kind of equipment used to process fiber materials. Its main working mode is to screen fiber materials before and after crushing through vibration screening. This equipment usually adopts a vertical structure, so that it can perform vibration screening operations more stably during operation. During the operation, the fiber material is first crushed and then enters the vertical fiber crushing and screening equipment. The equipment separates the fiber material into different particle sizes by vibration screening, thereby realizing the screening and grading of the material. This screening method can effectively separate fibers of different particle sizes in the material to meet the required quality and particle size requirements.
[0003] However, when the vertical fiber crushing and screening equipment screens the fiber materials by means of vibration screening, the fiber materials of different thicknesses and diameters will be screened out layer by layer in a vertical manner. During vibration screening, the vibration generated by the vibration motor acts on the screening box, causing the screening box to vibrate synchronously and screen out qualified fiber materials by means of vibration screening. During vertical vibration, if the fiber material is heavier, the vibration amplitude will be too small, while if the fiber material is lighter, the vibration amplitude will be too large. In particular, when the vibration screening amplitude is too large due to the lighter fiber material, the screening box will produce a larger range of vibration deflection, which will easily cause the material to be thrown out of the screening box, and the fiber material that does not meet the screening requirements will be screened out through the discharge hopper, which will cause most of the screened fiber materials to be unqualified. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] The utility model provides Figure 1-4 A vertical fiber crushing and screening device shown in the figure comprises a vibration support cylinder 2 and a top mounting flange 4 arranged outside the top of the vibration support cylinder 2, a bottom mounting flange 1 is arranged outside the bottom end of the vibration support cylinder 2, a plurality of vibration springs 13 are arranged equidistantly on the top of the top mounting flange 4, a packaging bottom plate 5 is connected to the top of the plurality of vibration springs 13, both ends of the vibration springs 13 are fixedly connected to the packaging bottom plate 5 and the top mounting flange 4 respectively by screws, a screening box A6 is arranged on the top of the packaging bottom plate 5, and a Screening box B7, screening box C8 is arranged on the top of screening box B7, screening box D9 is arranged on the top of screening box C8, screening box A6, screening box B7, screening box C8 and screening box D9 are fixedly connected to each other by flanges and screws, screening box A6, screening box B7, screening box C8 and screening box D9 are interconnected, screening box A6, screening box B7, screening box C8 and screening box D9 are arranged on the outer wall of screening box A6, screening box B7, screening box C8 and screening box D9, and screening box A6, screening box B7, screening box C8 and screening box D9 are arranged inside. There is a screen 14, and the screen 14 is inclined toward the discharge hopper 12. The top of the screening box D9 is provided with a top cover 10, and the top of the top cover 10 is provided with a feeding port 11. The bottom of the packaging bottom plate 5 is provided with a vibration transmission seat 15. The bottom end of the vibration transmission seat 15 is located inside the vibration support cylinder 2. The bottom of the vibration transmission seat 15 is fixed with a vibration motor 16 through a flange and screws. The vibration motor 16 is electrically connected to an external power supply through an electric wire. When using the vertical fiber crushing and screening equipment, first, the vibration support cylinder 2 needs to be passed through the bottom of the bottom The bottom mounting flange 1 is placed on the ground or a special table, and then the bottom mounting flange 1 is fixed with screws, and then the screening box A6 needs to be fixed on the packaging bottom plate 5 with screws, and then the screening box B7, screening box C8 and screening box D9 are installed in sequence, and finally the top cover 10 needs to be fixed on the top of the screening box D9 with screws, and the feeding port 11 at the top of the top cover 10 can be manually fed, or the feeding port 11 can be connected to the external material conveying pipeline with screws, and finally the vibration motor 16 needs to be powered on.
[0021] like Figure 1 and Figure 2As shown, when the vertical fiber crushing and screening equipment is working, the fiber material to be screened is put into the screening box D9 through the feeding port 11, and the vibration motor 16 is started at the same time. The vibration generated by the vibration motor 16 when working will be transmitted to the packaging bottom plate 5 through the vibration transmission seat 15, so that all the screening boxes will be driven to vibrate synchronously, and the packaging bottom plate 5 is installed on the upper end of the vibration support cylinder 2 through multiple vibration springs 13, so the vibration spring 13 will further enhance the vibration effect, and the mesh diameters of the screens 14 inside the screening boxes D9, C8, B7 and A6 decrease gradually. Under the action of vibration, the fiber material put into the screening box D9 will be screened by the vibration effect, and the fiber material that cannot pass through the screen 14 inside the screening box D9 will be transported toward the discharge hopper 12 by the vibration effect, and finally the screened fiber material will be discharged through the discharge hopper 12, and the screening method of the screening box C8, B7 and A6 is the same as that of the screening box D9, so fiber materials of various diameters will be classified and screened out.
[0022] like Figure 1 , Figure 3 and Figure 4 As shown, a polarization amplitude limiting device 3 is arranged on the outer side of the upper center of the vibration support tube 2, and the polarization amplitude limiting device 3 includes a horizontal bracket 17, an adjusting screw 18, an adjusting slot 19, a fixing sleeve 22 and a position locking nut 23. The fixing sleeve 22 is sleeved on the outside of the vibration support tube 2, and the fixing sleeve 22 is fixedly connected to the vibration support tube 2 by screws. A plurality of horizontal brackets 17 are equidistantly arranged on the outer wall of the fixing sleeve 22, and an adjusting slot 19 is arranged inside the horizontal bracket 17, and the adjusting slot 19 is inserted with the adjusting screw 18, and the outer thread sleeve of the bottom end of the adjusting screw 18 is sleeved with the position locking nut 23, the polarization amplitude limiting device 3 also includes a rubber protective sleeve 20 and a limiting column 21, the limiting column 21 is welded to the top end of the adjusting screw 18, and the limiting column 21 is arranged in a vertical state, the outer side of the limiting column 21 is sleeved with a rubber protective sleeve 20, and the rubber protective sleeve 20 is made of soft rubber.
[0023] like Figure 1 , Figure 3 and Figure 4As shown, the adjustment screw 18 can move back and forth in the adjustment slot 19, the diameter of the limiting column 21 is larger than the width of the adjustment slot 19, and after the position locking nut 23 is tightened, the top outer wall and the bottom outer wall of the limiting column 21 are tightly clamped on the bottom outer wall and the top outer wall of the horizontal bracket 17 respectively. When the fiber material put into the screening device is light in weight, the vibration motor 16 transmits the vibration of the screening box through the vibration transmission seat 15 to be too large, causing the packaging bottom plate 5 to drive the screening box to vibrate outward with too large an amplitude, which will easily cause the screening effect to be weakened and most of the fiber materials to be lost. The situation that the three-dimensional material cannot be screened out occurs, so at this time it is necessary to use the polarization amplitude limiting device 3 to limit the polarization range of the column 21 packaging base plate 5 and the screening box. Specifically, it is necessary to loosen the position locking nut 23 on the outside of the top of the adjusting screw 18, so that the position locking nut 23 changes from the original state of tightly squeezing and abutting against the bottom of the horizontal bracket 17 to a falling state, and then it is necessary to hold the rubber protective sleeve 20 on the outside of the limiting column 21 and push the limiting column 21 toward the packaging base plate 5. At this time, the adjusting screw 18 at the bottom of the limiting column 21 will be inside the horizontal bracket 17. The limiting column 21 moves in the adjustment slot 19 of the upper part toward the packaging base plate 5, and stops moving when the distance between the limiting column 21 and the packaging base plate 5 meets the polarization amplitude range that needs to be controlled. Then maintain this state and use an adjustable wrench to tighten the position locking nut 23, so that the position locking nut 23 and the limiting column 21 are tightly clamped and abutted against the outer walls at both ends of the horizontal bracket 17, thereby locking the position of the adjustment screw 18 to ensure that the limiting column 21 can always work in this position, and then adjust the other multiple limiting columns 21 in the same way, and finally the vertical fiber can be started normally. In the crushing and screening equipment, during vibration screening, the packaging bottom plate 5 will drive the screening box to screen the fiber material by vibration. When the vibration amplitude is too large, the packaging bottom plate 5 will be polarized outward over a large range and distance. However, when the packaging bottom plate 5 contacts the rubber protective cover 20 outside the limiting column 21, the limiting column 21 will prevent the packaging bottom plate 5 from driving the screening box to continue to polarize outward, thereby limiting the polarization amplitude of the screening box driven by the packaging bottom plate 5, so that the packaging bottom plate 5 drives the screening box to screen the fiber material by vibration screening within a fixed range.
